Answer:
so all x's have to be added together.
8x+5x+10x+7x=30x
-2+3=1
1dividedby30=30
x=30
hope this helps

x=15
Step-by-step explanation:
Substitute the values to check your answer...
(x²-11x)=60
(15²-11*15) =60.
R = laps she runs
s = laps she swims

each s (laps she swims) takes 3 min.
She wants to run for 30 min.
